The quests don't have great replay-ability due to the fact that most quests are linear and don't have multiple endings. It feels like the only branching in the game's quests come from the Civil War quests and those aren't even that good.

Gee thanks for the warning....My highest level character is a level 26 Bosmer Archer with 77.14.09 hours. I have completed 3 quests. 2 in the MQ, and 1 side quest. I'm counting 20 Misc Objectives Complete.
I have found 123 locations and have cleared 20 dungeons. I explore, collect ingredients for alchemy, hunt, mine, and do crafting. I'm having a blast.
I better keep doing what I'm doing so I don't get bored, because if the quests are boring, I might just have to stay away from all those needy citizens.

I've done a few other quests with my other two characters...and I don't really find them that boring. [edit] Sorry, "DULL".
But OP, you just need some fresh air, and to stop trying to please everybody...heh heh.
